Iosco County, MI Water Table Trend
Iosco County, MI: the closest actual trend
Huron County, MI, 42 miles from Iosco County, is the closest county with a qualifying well, and its water table is holding roughly steady.
No well inside Iosco County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Iosco County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Huron County, MI's full page. See the no-data guide for why a county this close to a qualifying well still doesn't get its own number.
